If you have health and dental insurance through your job but need expensive work done, can you purchase extra?

insurance from a different company to help cover the cost??
--------------------
Let's think about this for a minute. You know you need $10,000 worth of work. Your insurance is only going to cover say, $6,000 of the bill. So you're wondering if you can find an insurance company that if you pay them a premium of say, $150, they'll cover the other $4,000? That's not much of a deal for the insurance company is it? Do you really think they're going to issue you a policy knowing it's going to cost them $3850?
